Hi Abhiprae Choudhury,
>>Is there any equivalent in visual studio 2013? I want to create an extension in visual studio 2013, I found VSIX Project but couldn't find custom command in add item menu.
Yes, visual studio vsix project have a wizard, which you could select menu command, Please select
Extensibility -> visual studio package -> OK - > Next -> Next -> Next -> select menu command -> Finish


Best regards,
